Minnesota Historical Society launches MNOpedia

The popularity of Wikipedia may have forced Encyclopedia Britannica to stop publishing its 32-volume set after 244 years, but Wiki sources have never gained the trust of teachers. Now the creators of MNopedia–the state’s first digital encyclopedia–have built a website that is both reliable and interactive. KFAI producer Susan Gray spoke with Jim Ockuly and Molly Huber at the Minnesota Historical Society about how MNOpedia’s digital content is collected and shared.

Orfield Labs and the Anechoic Test Chamber

Founded in 1971 by Steve Orfield in Minneapolis, Orfield Labs is the only sound-quality laboratory in the United States. This internationally recognized lab is known for its design, research and testing services, as well as its ground-breaking research in science, perception and architecture of living facilities for elders and people with autism. The lab also provides services in acoustics, vibration, vision, lighting and more. The building has been recognized with two Guinness Book of World Records: The Anechoic Test Chamber—the Quietest Place in the World at –13 decibels; and Sound 80 Studios—the world’s first multitrack digital recording studio. Sound 80 has produced recordings by the St. Paul Chamber Orchestra, Bob Dylan and Prince. Today it’s used for research, testing and seminars. This story was produced for KFAI by Dixie Treichel.
